Weather in September
Temperature
The shift into September uncovers an average high-temperature of a still tropical 87.6°F (30.9°C), subtly different from the previous month. Gallion, during the nights of September, experiences an average temperature drop to a refreshing 67.1°F (19.5°C).Heat index
The heat index for September is calculated to be a very hot 100.4°F (38°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Heat index determinations are made taking into account the shade and light air movements. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection.
